When it comes to only friendship, definitely. I'm a male, and there are certain subjects that I just wouldn't feel comfortable talking about with a female friend, but that a male will understand easier. The same could be said for the reverse. This doesn't mean that I won't have a close friendship with a girl. I've had a pretty close female friend before who I treated and thought of like a sister. But I just couldn't get myself to talk about certain things with her that are quite natural when talking to males, at least for me. Their looks are, frankly, quite irrelevant for me.
